The use of controlled Cleanrooms is necessary in areas such as food and drug production, as well as the manufacturing of certain products. Contaminants in Cleanrooms are tightly controlled to avoid negative effects on said products being made. Total Clean Air provides Cleanrooms that comply with the various standards set by the International Organization for Standardization. Our Cleanrooms comply with ISO 14644 standards on air cleanliness, which were established to address the need for uniform Cleanroom classification and testing.
Modular Cleanroom Benefits

- Quick Assembly Time
- Airflow Control
- Inexpensive Modifications
With ISO 14644-3, the testing methods are divided into two different types: unidirectional flow and nonunidirectional flow. Cleanrooms can be assessed in three states: immediately after construction, during periods of no activity, and when fully operational. Total Clean Air Cleanrooms are tested by ISO standards across the board. In addition, clients can specify other types of testing to be carried out on the facilities, depending on their preferences.
The testing standards provided in ISO 14644-3 are geared towards ensuring there is an internationally recognised and accepted framework for measuring and assessing airborne particulate cleanliness in Cleanrooms, while ISO 14644-9 classifies particulate contamination on clean surfaces. The ISO framework also takes into consideration the importance of innovation and makes provisions for new testing and Cleanroom technologies.
Testing also defines performance parameters, allowing for different testing methods to be applied, depending on the type of Cleanroom or clean zone. As expected, our Cleanrooms are regularly tested to ensure continued compliance with the classifications outlined in Part 1 of the ISO 14644 standards.

Criteria for Maintaining a Cleanroom
Cleanroom operators look to ISO 14644-5 for guidance to ensure products manufactured in Cleanrooms are of high quality and exceed customer expectations. This section of the ISO standards deals with protocols involved in the operation and maintenance of Cleanrooms to minimise contamination risks. These criteria are applicable to all Cleanrooms and controlled environments, regardless of type or function. There are six major annexes covered by the standards, including: operational systems, clothing, personnel, stationary equipment, mobile equipment and cleaning.
Operational systems include the basic structures involved in the creation of products in Cleanrooms. In evaluating operating systems, managers must consider various factors, such as operational procedures, maintenance records, risk assessments, training, safety records, and modifications or upgrades. In Annex A of ISO 14644, information is provided with regards:
- Safety programs
- Subjects to be covered in training modules
- Factors to be considered in modifying or upgrading a Cleanroom
- Procedures for maintenance and monitoring of machines
It’s important to consider that special clothing is required to prevent contamination by personnel handling products in Cleanrooms – and in some cases, protect the personnel from such products. In many Cleanrooms, staff moving in and out are the major potential sources of contamination. This makes the choice of clothing an essential aspect of Cleanroom function.
Three factors are considered when choosing clothing for Cleanroom personnel: safety, product sensitivity and the classification of Cleanroom. Annex B of ISO 14644 discusses the design and construction of garments for Cleanroom personnel, taking into consideration factors such as particulate control, temperature, electrostatic, as well as any storage issues.

Annex D of ISO 14644 deals with stationary equipment in Cleanrooms. Equipment is another major source of contamination and must be carefully moved in and out of the Cleanroom. It’s important to consider the decontamination of equipment and method of transportation into the Cleanroom. It’s also essential to monitor installation procedures to minimise contamination risks.
For portable or mobile equipment, movement in and out of the Cleanroom must be monitored to minimise contamination. Maintenance and repair are also addressed in the annex. Emphasis is placed on maintenance before the equipment becomes contaminated and ensuring contamination controls are adhered to during the maintenance or repair process. Annex E provides information about cleaning tools, waste disposal, surface decontamination and site operational procedures.
In Annex F, operators can find standard cleaning methods, contamination tests, personnel training and cleaning schedules. The annex covers routine cleaning procedures, as well as cleanings during special situations such as construction and maintenance.
At Total Clean Air, our operational managers are well-equipped and experienced in maintaining Cleanroom standards, ensuring your products are manufactured in a safe and contamination-free environment.
ISO 14644-4 and 14644-5 outline the differences between Cleanrooms and separative devices in terms of construction, installation, testing and maintenance. These devices include mini-environments, isolators, and clean air hoods. At Total Clean Air, we provide and manage separative devices with open or closed systems. Our devices are manufactured to the highest standards and fitted with proper air filters and filtration systems.
Since ISO 14644 does not specify certain requirements for separative devices; we make all decisions upon consultation with our clients, while devices are manufactured according to the clients’ specifications. This covers areas such as installation, operator requirements, protective clothing and safety regulations. Whilst building in accordance to the customers’ specifications, we strive for quality and excellence in all our separative devices.
